FLYING-MACHINE.

Specification of Letters Patent.

Pat :nted May 1'7, 19.21.

To all whom it may concern.

Be it known that I, DANIEL FENSKE, a citizen of Canada, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Flying-Machines, of which the following is a specification.

This invention relates to improvements in flying machines and more particularly to helicopters. One object is to provide a machine of this type that is simple in construction, eflieient and safe in operation and relatively cheap to manufacture. object is to provide a machine of this type in which orpropellers are adjustable to graduate the speed of an ascent or descent and to determine the direction thereof, that is, whether perpendicular or oblique. t

With the foregoing and other objects in view the invention consists in the combination and arrangement of parts to be hereinafter fully described, pointed out in the appended claim and illustrated in the accompanying drawings which form a part of this specification and in which- Figure 1 is a view of my improved flying machine in side elevation. I

Fig. 2 is a section taken on Fig. 1.

Fig. 3 is a vertical sectional vlew at right angles to Fig. 1.

Figs. 4 and 5 are enlarged fragmentary sectional views illustrating the wing tilting mechanism, said views being disposed at ri 'ht angles, one to the other.

ike reference characters denote correline 2-2 of "spending parts throughout the several views.

The reference numeral 1 denotes the basket of the machine arranged upon legs 2 which are provided with the shock absorbers 3 to assimilate the impact when a landing is made. The basket is provided, further, with the rudder 4 controlled by the hand lever 5, and with the motor 6. The motor shaft 7 is connected by bevel gears 8 with the rotary sectional shaft 9, 10, the sections of which are connected by the uni-' versa-l joint 11. The shaft section 9 has its A further the lifting and supporting wings in said sleeve, teeth angle with the floor of the basket fiiced While a the shaft section 10 is adjustable with relation to the section 9 by means of the sleeve support 12,in which said shaft section rotates, and link 13 which connects said sleeve support to the screw shaft 14, jou-rnaled'in supports 15 carried by the basket, said screw shaft being operable by its handle 16.

For a perpendicular ascent or descent the shaft sections 9, 10 are retained in alinement by means of the screw shaft 14 and connect1ons. For an oblique ascent or descent the shaft sectiom 10 is disposed out of alinement with the section 9. This'operation is performed by rotation of the screw shaft handle 16. The speed of the ascent or descent is controlled in the following manner: The sleeve support 12 is formed along one face with the teeth 17 over which the pawl of the hand lever 18 works, said hand lever being fulcrumed to the sleeve support and connected by pitmen 19, 20 to the rotary block 21 that is keyed to and rotates with the shaft section'lO, the said pitmen 19, 20 being will operate to dispose the wings 24, 25 hori-.

zontally or atan angle to the horizon. In the horizontal position the machine will be caused to rise or descend slowly while in a position .at an angle to the horizon the ascent or descent will be more rapid, the greater the angle the greater the speed.

What is claimed is:-

' In a. flying machine, a basket, a motor driven sectional shaft carried by said basket, a sleeve support, one shaft section rotating formed along one face of said sleeve support, a hand lever fulcrumed to said sleeve support and formed with a pawl in engagement with the teeth of said sleeve support, a block slidably keyed to the last named shaft section and rotating therewith, pitmen connecting said block ture in the presence of two subscribing witand hand lever, and shafted wings carried nesses;

b said block and adjustable relatively I tii ereto through movement of said block rel- I DANIEL K 5 ative to its shaft section. W1tnesses:

In testimon that I claim the foregoing JOHN C. KLEIST,

as my own I ave hereto aflixed my signa- SAM. FRIEDBERG.
